We rejoice in the joys of our friends as much as we do our own, and we are equally grieved at their sorrows. Wherefore the wise people will feel toward their friends as they do toward themselves, and whatever labor they would encounter with a view to their own pleasure, they will encounter also for the sake of their friends.
Love between man and man is impossible because there must not be sexual intercourse and friendship between man and woman is impossible because there must be sexual intercourse.
I have always laid it down as a maxim -and found it justified by experience -that a man and a woman make far better friendships than can exist between two of the same sex -but then with the condition that they never have made or are to make love to each other.
